A mainstream (previously called read intensive) solid-state drive (SSD) might be reporting a change in status for the number of write operations that are available.

To determine the service action, complete the following steps:

  1. If the system has logical partitions, complete this procedure from the logical partition that reported the problem.
  2. Sign on to an IBM® i session with the QSECOFR user profile.
  3. To create a mainstream SSD report in a spool file, type the following command at the XPF command line and press Enter:
    CALL PGM(QSMGSSTD) PARM('SSDGAUGE' X'00000008' 'SSTD0100' X'00000000')

    Display the contents of the spool file. The spool file contains a report for mainstream SSDs. Then, continue with the next step.

  4. Use the resource name and part location from the serviceable event view to locate the mainstream SSD in the report. Are you able to locate the mainstream SSD in the report?
    • Yes: Continue with the next step.
    • No: Continue with the next failing item in the failing item list. This ends the procedure.
  5. Does the report for the mainstream SSD indicate that an error occurred in the collection of status information for the drive?
    • Yes: The status for the number of write operations that are available could not be determined. Continue with the next failing item in the failing item list. This ends the procedure.
    • No: Continue with the next step.
  6. Is the value in the Life Remaining Gauge field less than or equal to 2 percent?
    • Yes: Continue with the next step.
    • No: The mainstream SSD is not reporting a change in status for the number of write operations available. Continue with the next failing item in the failing item list. This ends the procedure.
  7. Is the value in the Life Remaining Gauge field 0 percent?
    • Yes: Continue with the next step.
    • No: Continue with step 9.
  8. The mainstream SSD reached the limit for the number of write operations that are supported. Write operations to the SSD become slower over time, and at some point the SSD becomes a read-only drive. When the operating system writes to a read-only drive, the write operations are rejected, and the operating system considers the drive as if a failure occurred. For example, if the operating system writes to a drive that is in a RAID array and if the write operations are rejected, the array becomes exposed. To support normal write operations, the drive must be replaced.

    Replacement of the mainstream SSD might not be covered by the system's level of service entitlement, depending on the terms and conditions of the system. For more information about mainstream SSDs, see Mainstream solid-state drives. This ends the procedure.

  9. The mainstream SSD is nearing the limit for the number of write operations that are supported. The reference code that sent you here is logged several times before the write operation limit is reached. No service action is required at this time.
    Note: After the mainstream SSD reaches the limit for the number of write operations that are supported, write operations to the SSD become slower over time, and at some point the SSD becomes a read-only drive. To support normal write operations, the drive must be replaced. Replacement of the mainstream SSD might not be covered by the system's level of service entitlement, depending on the terms and conditions of the system. For more information about mainstream SSDs, see Mainstream solid-state drives. This ends the procedure.
